摘要:
Embodiments of the invention use a gas flow to prevent adherence of a coating to portions of an engine block adjacent to a cylinder bore being coated with the coating. Embodiments may be particularly useful for applying a coating on the inner surface of the cylinder bores in one cylinder bank while protecting cylinder bores in an opposing cylinder bank, e.g., in a V-type engine. One method of applying a coating to an engine block comprises spraying the coating on an inner surface of a first cylinder bore of the engine block. The method further comprises shielding a second cylinder bore of the engine block from the sprayed a coating with a gas flow while spraying the coating on the inner surface of the first cylinder bore.

摘要:
An engine block coating system for applying a coating to an engine block includes a work stand, a coating gun, and a first nozzle. The work stand supports the engine block. The coating gun discharges coating on an inner surface of a first cylinder bank. The first nozzle discharges gas from a second cylinder bank to a crankcase side of the first cylinder bank and the second cylinder bank such that the second cylinder bank is shielded from the coating. The coating gun and the first nozzle are arranged relative to each other such that gas discharged by the first nozzle is discharged toward the coating to alter a direction of the coating by the gas discharged by the first nozzle directly contacting the coating such that the coating would otherwise contact the cylinder bore of the second cylinder bank upon stopping discharge of the gas by the first nozzle.
摘要:
The adhesiveness of a thermal spray coating and a cylinder internal surface is improved by forming a sufficient roughened surface on an internal surface. A processing roller is installed on the main shaft of a processing device via a pressurizing mechanism. An uneven surface is provided on the external periphery of the processing roller. By pressing the processing roller against the internal surface while the roller rotates and moves, a fine unevenness that corresponds to the unevenness of the roller is formed on the cylinder internal surface. A thermal spray coating is formed on the internal surface where the inner surface has been roughened by forming the above-mentioned unevenness.

A prespray processing method includes preparing a work surface for spray coating, roughing the work surface by pressing a tool against the work surface, having a material of the work surface displaced thereon to form a depression thereinto, and keeping the material of the work surface unremoved therefrom.

An image forming apparatus includes a forming section that forms an image on a side of paper; a fixing section that applies heat to fix the image onto the side of the paper; a paper reversing section that reverses a front and back of the paper having the image fixed onto a first side in the fixing section; a first measuring section that is provided between a registration roller and the forming section to measure a first moisture content of the paper before an image is formed on the first side, and a second moisture content of the paper before an image is formed on a second side, after the image is fixed on the first side; and a calculating section that calculates amount of change of the size of the paper on the basis of the difference between the first moisture content and the second moisture content.
摘要:
The present invention provides a compound a piperidine derivative having excellent histamine receptor antagonistic action, which is useful as active ingredients of a pharmaceutical composition, especially an antihistamine. The piperidine derivative of the present invention has a potent histamine receptor antagonistic action. Further, the compound of the present invention shows low brain transfer even in a cerebral receptor binding test where a mouse is orally administered with the compound, so that the compound has preferred properties of alleviating side effects in the central nervous system, such as drowsiness. The piperidine derivative of the present invention is very useful as a novel antihistamine having smaller side effects in the central nervous system, such as drowsiness.
